Application filed January 13, 1917. Serial IMO-142,194.

To all cohort may concern:

' ing' the tops of butchers and leather workers chopping and cutting blocks.

One object of my invention is to provide a device of the above described type which will include a power driven brush, and to inelose the brush within a hood or casing.

Another object is to so construct my invention'that it can be firmly held in contact with the article being cleaned.

A still further object is to make my invention of simple construction,-and so that it can be easily manipulated.

These objects, and other advantageous ends which will be described hereinafter, l, attain in the following manner, reference beinghad to the accompanying drawings in which-- s v Figure 1 is a plan view of my invention.

Fig. 2 is an elevation of Fig. 1 showing certain of the parts in section.

Fig. 3 is a plan view of a brush which I employ, with its cover plate removed.

Fig. 4 is a fragmentary perspective view showing how the adjustable portions of my improved casing are formed.

Fig. 5 is, an enlarged fragmentary section taken on the line 5-5 of Fig. 3.

Referring to the drawings, 1 represents an electric motor including a rotatable shaft 2 which is screw-threaded at its outer end 3 for engagement with a tapped hole 4 in the brush supporting plate 5. The plate 5 has a plurahty of holes 6 extending therethrough, and throughthese holes extend metallic bristles 7 (see Figs. 3 and 5).

These bristles are ll-shape and upper ends 8 of said bristles project beyond the sipper face 9 of the plate 5. Wires 10 extend across the surface and under the ends 8 of the bristles 7, and

. thereby form a lock toprevent the downward movement of the bristles.

. A cover plate 11 is secured to the plate 5 by means of screws 12, and this cover'plate. has a recem 13which provides flanges 14: for

" spring steel wire so the brush is rotated.

. from'time to time as folded 9 of the plate 5 engagement with the upper surface 9 of the plate 5. and also provides room for inclosing the wires 10 and the upper ends of the bristles 7. By this construction the cover plate .11 protects the upper ends of the bristles and also prevents. upward movement thereof.

= The bristles 7 that their lower ends form a plurality of cutting edges or knives and are of suflicientjstrength to cut or pare a wooden block or. other similar article when The upper surface of the coverplate 11 is spaced from the motor 1 by means of a' sleeve 15 which is attached to the motor and forms an abutment for said upper "surface of the cover plate 11. This same spacing alsoprovides room for a head plate'16 which 75 forms a part of a hood or casing 17 "for, the brush. The casing 17 has a Mrt 18 which is made in two circumferentially extending sections 19 and 20. The section 19 is secured to the head plate 16 as shown at 21 by a lapped or interlocking joint. The section 20 slides or telescopes within the section 19 and is provided with slots 22 (see Fig. 2). v v

Bolts 23 extend through the slots 22 and through holes 24, and at their outer ends" are provided with butterfly nuts 25 wherebyv the section 20 may be clamped to thesection 19. Also, by this construction, as the bristles 7 wear down and become shorter, the section 20 may be slid within thesection 19.

and in proportion to the I thus provide an adjustable hood or casing which surrounds the brush and in action this casing prevents the particles as they are cut from flying uncontrolled over the surface of the article being cleaned or resurfaced.

In othervwords, the casing 17 acts to confine the particles as they are cut or removed by the brush.

The motor 1 has laterally extending cars 26 which are diametrically opposite each other with respect to theaxis of the shaft 2, and these cars form supports for two handles 27 and 28.v Bolts 29 extend through the cars 26, handles 27 and 28, and the head plate 16 of the casing 17 so that the handies and casing 17 are securely held to the motor.

The motor may be rotated by current sup-' plied through the medium of the wires 30 wear of the bristles 7.

are preferably made of flat ends of the bristles 7 what is known as and plug 31 said wires be preferably in the form of a flexible cable so that the device may be freely moved without interference.

. Thehandles 27 and 28 have ends 27 and. '28 which extend inwardly beyond the bolts 29 and closely hug the motor (see Fig. 1). By this construction it is impossible for the handles '27 and 28 to swivel or turn on the bolts 29, andlt thus provide a firm handheld and prevent the handles from becoming 2b merely by starting the motor 1 to rotate the brush and by Holding the device by the aid of the'handles suficient pressure may be attained between the cutting or cleaning and the block which is being cleaned.

e I have described my invention as a particular 'fo, it will be underr aee eae tion may be changed without departing from the spirit thereof, and hence I do not t myself to the precise construction set forth;

but consider that l am at liberty to make such changes and alterations as fairly come within the scope of the appended claim.

Having thus described my. invention, what ll claim as new and desire to secure by Letters Patent is: v

The combination of a rotatable b a motor for rotating-the brush, handles, bolts connecting the handles and the motor together, said handles having portions extend ing inwardly from said bolts and operative to abut the motor and thereby prevent pivotal movement of the handles with respect to the bolts, substantially as described.

In testimony whereof I have signed my (name to this specification in the presenceof two subscribing witnesses.

Louis Esouronnn.
